Gruppe: C4215
JOYIN Metal Oxide Varistors
Series: JVR
Style: Taped, Bulk
Pitch: 5/7,5/10mm

Features
• Used as voltage-dependent resistors (VDR's) to protect electronic devices
• They protect against overload build-up and protect valuable equipment from power surge damage
• Surge voltages are absorbed in the varistor
Selection Criteria
• The maximum operating voltage must be lower than the varistor voltage.
